A novel on-line detection method to monitor the short-circuit reactance of three-phase transformer
摘要
Abstract
The online diagnose on the condition of the transformer is of great importance to find the hidden peril of faults about transformer as soon as possible , as well as prolong the working life of transformer and keep the safe and reliable operation of the power system .The transformer short-circuit reactance is affected by winding geometry , spatial location and so on .When winding deformation of transformer happening , the short-circuit reactance will be changed accordingly .In this paper , a new way of calculating the short-circuit reactance of three-phase transformer during its operating state is proposed directly , meanwhile , it also can conduct online detection for the winding deformation of transformer.The simulation and experimental results verify the effectiveness and feasibility of the proposed method .关键词
